Stroke: After the thrombus is removed, blood pressure variability is closely related to the poor prognosis

In the vessel the stroke within the first few hours after the treatment (the EVT), blood pressure (BP) elevated increased risk of hemorrhagic transformation, the result is worse

As the brain's auto-regulatory function is impaired, it is easy to cause low or high brain perfusion.

Traditional blood pressure variability measurement usually requires 24-hour blood pressure monitoring, which limits its role in clinical decision-making

In this way, Pedro Castro et al.

They conducted a prospective study of 146 patients with anterior circulation ischemic stroke who successfully received endovascular treatment

Clinical outcome: including the initial clinical response and the modified Rankin scale after 90 days

They found that the increased frequency of blood pressure variability was independently associated with the dysfunction at 90 days (adjusted probability aOR=1.

After adjusting for baseline severity, higher normalized high frequency (aOR=1.

Higher normalized HF power and lower LF/HF ratio also reduced the possibility of nervous system recovery (aOR=0.

The important significance of this research lies in the discovery that high-frequency blood pressure fluctuations after successful reperfusion may be harmful and are related to the reduced possibility of nervous system recovery and favorable functional outcomes
